You should administer first aid only if trained and if there is no risk of injury. Be particularly careful of contamination by blood-borne pathogens. Do not administer CPR or use an AED unless specifically trained.
Plan ahead by documenting where your emergency supplies and first aid kits are located. Check regularly to ensure that these supplies are adequately stocked and their expiration dates are current. To prevent contact with bodily fluids, consider stocking latex gloves and protective glasses.
Take medical precautions and report any exposure to emergency personnel. Anyone who comes into contact with bodily fluids should wash the exposed area immediately with soap and water, and use water or saline solution to irrigate the eyes. Cleaning personnel are required to be trained with blood-borne pathogen kits.
